Public Member Functions

constexpr auto	operator() (R &&r) const
	Eagerly materialize the provided range into container type C.
constexpr auto	operator() () const
	Return a closure object for pipe usage syntax.

Detailed Description

template<typename C>
struct jh::ranges::collect_fn< C >

Function object implementing jh::ranges::collect.

Provides both direct-call and pipe-style interfaces for range materialization.

Direct call form

auto vec = jh::ranges::collect<std::vector<int>>(range);

Pipe form

auto vec = range | jh::ranges::collect<std::vector<int>>();

When the range is closable to C, this function uses jh::ranges::to_adaptor<C> internally; otherwise, it falls back to insertion/emplacement iteration.

Template Parameters

C	The target container type.
